Chrome

Since Chrome 31, you can set up your web app to have an application shortcut icon added to a device's homescreen, and have the app launch in full-screen "app mode" using Chrome for Android’s "Add to homescreen" menu item.

Homescreen-installed apps work exactly like you would expect a normal web application to work. They follow the same sandboxed security policies and have access to the same APIs; however, they integrate with the Android environment in the following ways.

When a user clicks "Add to homescreen", they will see the app being added on the homescreen.

Firefox

Firefox lets you create shortcuts on your Android's home screen so you can quickly access your favorite websites. It eliminates the need to type a web address every time you want to access the site - just tap on its shortcut to open the page.

Here's how to do it:

  1. Open Firefox for Android and go to your favorite web page.

  1. Press the Menu button (either below the screen on some devices or at the top-right corner of the browser) , then tap on Page.

  1. Tap Add to Home Screen.
